My stoneware ceramics are fired at high temperatures (1230ºC), making them so compact that they are not permeable to water at all. The clays and glazes I use do not contain any harmful substances, they are suitable for food.
The high quality materials I use allow them to be used in the oven, microwave and they are also all dishwasher safe.
Since every piece is handcrafted and unique, the sizes and patterns may slightly vary.
